Windows 11 Insider Preview Build 22635.4445 (KB5046745) arrived in the Beta Channel on November 8, 2024, for Windows 11 version 23H2. Its headline addition was a New Folder command in File Explorer’s navigation-pane context menu; the rest of the update focused mainly on taskbar, File Explorer, and Snipping Tool fixes. This is a historical preview-build report, not a current update recommendation.

What is Build 22635.4445?

Microsoft released Build 22635.4445 to Windows Insiders in the Beta Channel as KB5046745. It was delivered as an enablement package on the Windows 11 version 23H2 baseline. The build number identifies a Beta Channel preview—not a separate Windows edition or a new public feature update. Microsoft’s Windows Insider Flight Hub lists builds by channel and release history.

The November 8 announcement describes one modest user-facing addition and a set of reliability and usability fixes. It does not provide benchmark figures for the performance changes.

The new File Explorer command

In this build, right-clicking a location in File Explorer’s navigation pane can show a New Folder command. The pane is the folder-and-drive list along the side of File Explorer. The command provides another route to create a folder without first moving to the main file view or using the keyboard shortcut. It is a small workflow convenience, not a redesign of File Explorer.

The command was subject to a gradual rollout, so installing the build did not guarantee that every Insider would see it straight away. Microsoft said it was rolling the change out to Beta Channel users who had enabled Settings → Windows Update → Get the latest updates as soon as they’re available. Availability could still vary while the controlled rollout was in progress.

Key fixes in Build 22635.4445

Taskbar and Explorer reliability

Microsoft made reliability improvements to explorer.exe, the Windows process that handles the desktop shell, including parts of the taskbar and File Explorer. The build also addressed crashes that could occur when right-clicking apps on the taskbar. These are targeted fixes, not a broad taskbar redesign.

On some secondary monitors, users with a left-aligned taskbar could see Widgets text overlap the date and time. Microsoft said this build corrected that layout problem.

File Explorer behavior, appearance, and search

  • Copied-file dates and times: The build addressed an issue in which file date or time properties could be unexpectedly updated after copying files.
  • Details Pane theme icons: Icons in the Details Pane did not always respond properly when users switched between light and dark themes; Microsoft fixed that behavior.
  • Duplicated tabs: A black flash could appear when duplicating a File Explorer tab. The build addressed the issue.
  • Context menus and navigation: Microsoft included changes intended to improve context-menu launch performance and File Explorer navigation. No percentage improvement or benchmark method was published, so this should not be read as a quantified speed gain or a guarantee that all slowness was resolved.
  • Repeated searches: The update addressed a problem that could cause File Explorer searches to trigger repeatedly or unexpectedly.

Snipping Tool captures

The update fixed an underlying issue that could make Snipping Tool screenshots appear distorted on certain displays. Microsoft did not specify every affected display, resolution, scaling setup, or graphics configuration. If distortion persisted, it would not necessarily mean this particular fix had failed: display scaling, drivers, multi-monitor settings, or another capture issue could also be involved.

How to install it—and why that advice is historical

At the time of release, an eligible Insider could check for the build through Settings → Windows Update → Check for updates, after enrolling in the Beta Channel. The “Get the latest updates as soon as they’re available” setting related to the staged feature rollout. After installation and a restart, the build number could be checked in Settings → System → About or by running winver.

Build 22635.4445 was released in November 2024. It should not be expected as a current Windows Update offering simply because a PC is running Windows 11 today. For current Insider channel and build information, consult Microsoft’s Flight Hub.

Preview-build caveats

Beta Channel builds are test software. They can introduce problems, and features may be changed, removed, or never released to Windows users generally. A feature may also arrive gradually, meaning two devices on the same build can behave differently. The New Folder command’s absence alone would not establish that installation had failed.

Insider previews are better suited to enthusiasts, developers, and testers who can tolerate instability than to business-critical or primary work PCs where taskbar, file-management, display, or capture reliability is essential. Before installing preview software, back up important files and keep a recovery option available. If File Explorer acts oddly after an update, a restart or reboot is a sensible first check, but it is not a documented fix for every issue.

One nearby-build distinction is worth noting: the modernized Windows Hello experience was discussed in the preceding Beta Channel Build 22635.4440 announcement, not as a feature of 22635.4445. See Microsoft’s Build 22635.4440 notes for that change.
